To all whom t may concern.'

Be it known that I, ROBERT Lnwis BUR- ,GOON, a'citi'zen of the United States of Amerthat is slidably mounted upon the side of the 'car and seated in the doorway or frame ofthe car.

The primary object of my invention is to furnish a door of the above type with a novel lock that lpermit-s of the door being easily and quickly unlocked and shifted to an open position.

Another obj-ectof my invention is to yprovide a car lwith an anti-friction rail or track upon which acar door can be veasily and open the door -or close tie same.

A further object of this invention is to accomplish the above results by a mechanical construction that is applicable to various types of cars, strong and durable-and highly etlicientfor the purposes for which it is intended. y A

With the above and other objects in view, the invention resides in the novell construction, combination and arrangemnt of parts to be hereinafter specifically described and then claimed.

:Reference vwill now behad tothedrawing wherein like numerals denote corresponding` parts throughout the several vie-ws, in

which Figure 1 is a front elevation of a portion of a car, partly broken away and partly in section, illustrating by dotted lines the lock in an open position, Fig. 2 is a longitudinal sectional view taken on the line II-II of Fig. 1, Fig. 3 is a similar view showing the car door in an open position, Fig. 4 is a perspective view of a detached rail or track, Fig. 5 is a cross sectional view taken on the line V-V of Fig. 1, Fig. 6 is a similar view taken on the line VI-VI of Fig. 1, and Fig. 7 is a cross sectional view of they rail or track.

The reference numeral 1 denotes the side of a. car having an opening or doorway 2. The vertical walls of this doorway have the outer edges thereof chamfered or recessed,

cesses 19.

as at3 to receive the vertical side flanges el of a door 5, said door fit-ting in the doorway with the outer side of the door lliush with the outer side of the car.

The side of the car, at lthe upper edge of the doorway2,is pro-vided'with a longitudinal guide rail 6, `said rail having a horizontal flange 7 anda depending flange S. The rail 6 is bolted or otherwise secured to the side of the car, as` at 9 and the length Aof said rail is approximately ytwice the width of thel doorway 2, the horizontal liangeT of the rail is braced by equally spaced ribs or webs 10, and saidflange is provided with an opening 11 at a point approximately intermediate the side walls'of the doorway 2.

The bottoni of the doorway 2 is cut away to receive a-sill 12 carried by a horizontal antifriction rail 13. The rail 13 is the same length as the guide rail 6, and said rail has a back plate 111 secured by bolts l5 or other fastening means to the side of the car 1. The horizontal rail 13 is braced relatively to the back plate lll by equally spaced ribs or webs 16, and the forward edge of said rail has a vertical Yflange 17 with one end thereof curved or bent toward the side of the car, as at 18, the purpose of which will presently. appear.

The sill end of the horizontal rail 13 is provided with equally spaced transverse re-y cesses 2O and the opposite end of said'rail, which is of a less width than the sill end, is provided with equally spaced transverse re- Revolubly mounted in the recesses 19 and 20and protruding above the surface of the rail 13, are rollers 21 and 22, said rollers being retained within said recesses by bolts 23 and nuts 24.

The horizontal rail 13, between the recesses 19 and 20, is provided with drain openings 25, said openings allowing water, dirt and other matter to drain from the horizontal rail 13. The rail 13 has the sill pins 34 to locking bars 35S The bars' are loosely mounted in straps 36 and 37, the latter being carried by the outer side of the door and the former by the outer side of the housing 29. rlhe ends of the locking bars 37 are reduced to providerpiiis 38 adapted to enter the openings 11 and 26 of the rails 6 and 13 respectively'to'loclr the door 5 relatively to the side of the ear.-

Hinged to the T-bar 33', as at 39 is a hasp 40 adapted to iit over a staple k41 carried by a bar 42 secured to the door A seal 43, lock or other fastening device can be placed in engagement with the staple 41 to retain the hasp 40 in a locked position. i

The outer sideV of the door 5 is provided with a handle 44 adjacent to the lower edge thereof.

To open the door 5, the seal 43 is removed and the hasp 40 swung outwardly at. right angles to the T-bar 33. Using the hasp 40 as a'handle, the T-bar 33 is shifted to move the locking bar 35 whereby the pins 38 will be withdrawn from the openings 11 and 26. By gripping the handle 44, the door 5 can be shifted outwardly upon the rollers 22 and then shifted on to the rollers 21, the door being guided by the rails 6 and 18. The opening movement of the door is limited by the stop block 27.

Vhen closing the door 5, the curved end 18 of the flange 17 guides one edgeof the door into the doorway 2, and by pushing inwardly upon the handle 44, the door can be seated in the doorway 2. rlhe T-bar 33 can then be manipulated to lock the door in a closed position.

It is thought that the operation `and util ity of the car door will be apparent without further description, and while in the drawing there is illustrated a preferred embodiment of the invention, it is to be understood that the structural elements are susceptible` to such changes as fall within the scope of the appended claim.

A door sill for cars comprising a base plate of a length greater than the length of the door opening, one portion of said plate positioned at and adapted to extend into the door opening and of greater width than the remaining portion, a vertically disposed Vflange extending throughout the length of the plate along the outer edge thereof and terminating at theV rear edge of saidwider portion Yof said plate, a vertically disposed ange extending. along'the' inner edge of said wider portion ofsaid plate and terminating at one end of the inner edge of the narrow portion of said` plate, said latter liange being angulanin cross section and having its upper portion projecting rearwardly with respect to saidv wider portion of the plate, a depending apertured securing flange integral with the lower face of'said plate and disposed at the longitudinal center of said wider portiomsaid plate having its upper face provided lthroughout with transversely extendinglrecesses, rollers mounted in said recesses, .means connected with the vertical flanges for maintaining the rollers in position, that end ofsaid inner vertical flange terminating in the inner edge of the narrow part Vof saidplatebeing spaced from said outer vertical liange to provide a passage when shifting the door from the wider portion on to another por- 'tion of the plate.
